If you want a powerful GTD-style task manager, 2Do is what you need.

2Do - Todo List, Tasks & Notes

2Do: Tasks Done in Style offers a great middle ground for those looking for a lot of features but not looking to invest in OmniFocus or GTD. 2Do is extremely flexible and customizable, with a tab-based user interface that supports drag and drop rearranging of items, as well as multiple options for each item (e.g., users have the option to set a reminder as a message, sound, or email). 2Do can also fully integrate with iCloud, Reminders, and Siri: each tab in 2Do becomes a separate list in the default Reminders app and each Reminder is automatically added to 2Do’s Reminders tab. The only issue with 2Do is that it requires effort to master all of the app’s features, as it’s not very intuitive to use and does not have a straightforward help or tutorial section. This makes learning to use the app a task in and of itself!
-Syncs with: Toodledo, Dropbox, Caldav, Mac/PC, iCloud, Dropbox, Outlook via a helper app, supports email backup and export to CSV
-Additional Cost: None
-Reminders/Siri: Fully integrates with iOS Reminders and Siri with no extra setup required-- choosing iCloud sync automatically integrates everything

Groups, projects and lists. Whether you need groups, work with complex projects, or just want simple lists, 2Do has it all. This is a task manager that can be as simple as you need it to be, or you can go for something much more complex and complicated — it all depends on what you are looking for. It's flexible enough for everyone and can help you become more productive than ever before.

Organize by tags. Sometimes just grouping things into one category is not enough. With 2Do, you can organize your tasks with tags, which are easier to search for. View all of your current tags with a swipe, and then create new ones without having to add a new task first. 2Do will also autofill tags when you add them on tasks, making your life easier.

Many options for new tasks. When creating a new to-do item, you'll have a myriad of options for quickly adding a due date and time. Choose a default, or pick your own from the calendar and time spinner. You can also pull up information from your contacts and other cool stuff. 2Do is flexible and powerful.

What is it about?

2Do is a powerful and flexible to-do app for those who want a robust system with a lot of options and customization. It is best suited for those who deal with multiple projects, want to organize with tags, and need checklists or subtasks for certain tasks. Everything in 2Do can be customized, from the colors of projects to default due times, number of notifications and alerts, and so much more. If you are looking for a to-do app that will let you do things how you want to do them, then this is the app for you.

For those who...

It’s ideal for anyone who wants to get their tasks in order since it doesn’t adhere to any partial methodology.

Not for those who...

2Do has everything going for it, so the only reason to skip it is if you’re content with what you’re already using.
